That's probably a good idea.  I made some tests with generating a
heightfield from the photograph on

http://www.milton.com/praha2002/im000163.jpg

here is the result.  It surely does not look very good which is of course
partly because the photo is not that good for this purpose.  What helps is
that shading in our case is somewhat similar to the photo although with
more shallow lighting - otherwise you would not even recognize the rough
geometry.
